Proper Break-In Procedure:

Driven’s Break-in oil is very high in ZDDP (typical 2800-3000 PPM ZDDP) but its also very low detergent. Detergent will counter the ability of the ZDDP to adhere and protect the needed part. This is because ZDDP and Detergent are both surface active - they compete for the same space. On a brand-new engine, you just want to have ZDDP to form anti-wear protection without the detergent cleaning it off per say.

Run the Break-In oil for the first 30 mins - Change the filter/oil and replace with Break-In oil to flush out wear metals and assembly lubricants - run approx. 400 miles on break in oil – Change the filter and replace the Break-In oil with your usual Driven Racing Oil.

Driven GP-1 20W50 Break In oil should only be used for engine break in. This engine oil will NOT MEET any current API or OEM Engine Oil Specifications as it is formulated specifically for engine break in.
